| 广泛用于6KV~35KV电压等级的配电网中性点非有效接地系统.，电力、钢铁、煤矿、水泥、石油和化工等行业。 It is widely used in 6KV~35KV distribution network neutral point ineffective grounding system, power, steel, coal mine, cement, petroleum and chemical industries. 装置通过由微机控制器和PT组成的检测系统对系统的运行状态进行监测, 在系统线路中一旦发生弧光接地过电压，微机消弧控制器向故障相真空接触器发出合闸命令，故障相真空接触器快速动作，在2个周波内将弧光接地转化为金属性接地。故障点因弧光过电压为零而立即熄弧，非故障相过电压稳定在额定相电压，可以长时间安全运行（国家规程要求2小时）。当系统有操作过电压或大气过电压时,由组合式过电压保护器将过电压限制在系统绝缘允许的范围内。 The device monitors the running state of the system through a detection system consisting of a microcomputer controller and a PT. Once the arc grounding overvoltage occurs in the system circuit, the microcomputer arc suppression controller sends a closing order to the fault phase vacuum contactor, which acts quickly and transforms the arc grounding into metal grounding in two cycles. The fault point is extinguished immediately because the arc overvoltage is zero. The non-fault phase overvoltage is stable at the rated phase voltage and can operate safely for a long time (2 hours required by the national regulations). When the system has switching overvoltage or atmospheric overvoltage, the combined overvoltage protector limits the overvoltage to the allowable range of system insulation. 功能： Functions: 1.消弧功能:在系统发生弧光接地故障时,尽快熄灭电弧,防止故障进一步发展,避免固体绝缘设备的累积性破坏;允许用户在完成转移负荷的倒闸操作之后再处理故障线路,避免被迫停电; 1. Arc extinguishing function: When arc grounding fault occurs in the system, the arc should be extinguished as soon as possible to prevent further development of the fault and avoid cumulative damage of solid insulating equipment, allowing users to deal with the fault line after switching off the transfer load and avoiding forced power outage; 2.消谐功能:一次和二次相结合的消谐功能,快速抑制系统非线性谐振; 2. Harmonic elimination function: the first and second harmonic elimination function can quickly suppress the system's non-linear resonance; 3.单相接地选线功能:采用“群体比幅比相”的方法,迅速判断故障线路; 3. The function of single-phase grounding line selection: using the method of "group ratio of amplitude and phase" to quickly judge the fault line; 4.替代PT柜的的功能。 4. Replace the function of PT cabinet. 特点： Characteristic: 1.将弧光接地过电压限制在电网安全运行的范围之内,同时转移故障点,弥补了消弧线圈限制弧光接地过电压的不足,提高了电网的供电可靠性; 1. Limiting arc grounding overvoltage to the safe operation of power grid and transferring fault points at the same time make up for the shortage of arc suppression coil limiting arc grounding overvoltage and improve the reliability of power supply of power grid. 2.限制过电压的机理与电网对地电容电流的大小无关,保护性能不随电网运行方式的改变而变化; 2. The mechanism of limiting over-voltage is independent of the magnitude of the capacitive current of cangzhou.71ix.cnmiehuo.37ix.com.cnrunhuayou.89ix.comthe grid to the ground, and the protection tangshan.71ix.cnqinhuangdao.71ix.cnzhangjiakou.71ix.cnperformance does not change with the change of the operation mode of the grid. 3.装置的结构简单,动作可靠,体积小,安装、检修方便适用于各种电力系统的运行; 3. The device has the advantages of simple structure, reliable operation, small volume, convenient installation and maintenance, and is suitable for the operation of various power systems. 4.装置具有较高的性价比,可取代消弧线圈、接地变压器及其控制屏,对于新建工程还可省掉PT柜。 4. The device has high performance-price ratio, can replace arc suppression coil, ground transformer and its control panel, and can also save PT cabinet for new projects. 5.柜型可根据用户需求定做，满足用户并柜需求。 5. The cabinet type can be customized to meet the needs of users. |
